Introducing PIKA - Print In-place Kinematic Assembly

So here's what RepRapMicron stuff I've been working on. This is a replacement for the XY Table that prints in place. No support, no fasteners. In theory...

 

You might recognise it from a prototype I made in TinkerCAD. The two big differences here are that this is an actual parametric model, and the lower framework that holds the X axis has staggered flexure pairs to make it more compact.

This is gloriously unfinished. I have to work in the X & Y drive flexures, devise a sane way of attaching the Stage to the top in a way that allows it to be levelled, and add framework to attach the X & Y Axis Drivers (possibly Z and microscopes too), and make a base to lift the flexures off the ground. Probably going to integrate the Y drive flexure into the Stage for now, much like the X is done on Maus.

I've put the OpenSCAD files up on github in maus_pika.scad

Also, now I have the RepRapMicron repaired after the flight back, I can start playing with Siddharth's joystick code. As soon as I get back from a brief stay in Wellington. Damn it's busy.
